容错轮询系统分析模型

Analysis Model of the Fault-Tolerant Polling System

本文提出的多服务器轮询系统分析模型考虑了故障对系统性能的影响,特别适应于在任务级或传输子系统级评估分布式实时系统的响应特性,对容错分布式系统设计及系统重组策略的优化、选择具有指导意义。

This paper presents a polling model wieh multiple Server. In the model, we consider the effects of server failures on system performance. The model is applicable to evaluate response characteristics of distributed real-time systems at the level of tasks or tran smission subsystems. It is significant to reliability design of distributed system. It is also important to optimization and selection of the reconfiguration strategy in fault-tolerant distributed systems.
